### ⭐⭐⭐⭐⭐ Perfectos

### ⭐⭐⭐⭐⭐ Piccoli altoparlanto con cassa
*by P***I on 26 December 2023*

Vanno bene dove servono piccoli altoparlanti (0.5W circa). Hanno il vantaggio di avere una loro cassettina in plastica, questo facilita il montaggio e l'uso. Sarebbe ancora meglio se avessero una protezione sul davanti (retina, tessuto o simile).
